How much BHP does an M3 make ...

[anon37485]

I can't find a definitive answer, each article I read suggests something slightly different.

But out of curiosity, what's the BHP (equivalent) for the SR+, LR AWD, P+ Model 3?

From what I've seen:

Wiki
SR+ 283 bhp, LR 412 bhp, P 473 bhp
Tesla Model 3 - Wikipedia

Parkers
SR+ 241 bhp, LR 346 bhp, P 449 bhp
Tesla Model 3 Saloon (from 2016) specs, dimensions, facts & figures | Parkers

Anyone got other articles showing different/confirmed figures?

as you can see, it depends

your V5 will give max net power of motors but whether you are runnng at that power is anyones guess as software controls it

Ours is 350kW

 

[m3p_uk]

There have been 2 software/firmware updates to all models which have increased power output from the original which I'm guessing is what is Parker's have

I wish there was a definitive answer to this question, as it seems that there are a wide range of figures being bandied about, and I've no idea which may be true, or close to being true and which may be just plain wrong.

To make matters more confusing, the recent software update has apparently increased power by 5%, but 5% of what, I wonder?

Just taking numbers in this thread, it seem that the M3 LR could be anything from 346bhp to 469bhp. Such a wide range is bonkers, so there must be some really serious errors in some of the numbers.

The number given on the V5 is probably now in error, due to the software change, plus it may take no account of the way the software controls the power, either. There must be a way to find out, just for comparative purposes, the bhp, either at the motor shaft (roughly the same as at a flywheel) or at the wheels for a given set of conditions, other than just guessing from what looks to be flawed information on various web sites.

Is there any way to extrapolate a rough estimate based on vehicle weight and 0-60 times? A genuine question — I don’t know.

Really good question.

I’m not sure how accurate this is (maybe someone can use some other car figures to see it’s accuracy) but putting 1,800 kg weight and a 4.4 second to 60 (or should that be 62?) it suggests 489 bhp for the LR. And 316 bhp for the SR.

See what you think.

EDIT - it reckons the P is 780, so maybe it’s not that accurate hahaha.

It's quite simple, actually. Read your power meter. One HP is 745.7 W. Thus when the car is consuming 30 kW, which seems to be the nominal for cruise, it is taking 40 HP from the battery most of which (90%) reaches the motors.

So what’s the answer then?

 

[ajdelange]

Whatever your power meter tells you.

I don’t have one to tell me...

You don't? I can't imagine any BEV maker putting out a car without displaying real time power consumption and certainly not Tesla but if they don't display power in the 3 then you can't do what I'm suggesting. Sorry.

363 hp according to EV Database.

Tesla Model 3 Long Range Dual Motor

Found this thread searching for this information myself. Ironically, selecting the link above on the EV Database shows the LR as having 434bhp

Have a look at this video of a 2021 M3P on a dyno here which delivers 'around 523 BHP'. (Evidently, on the M3P at least, 'dyno mode' is key).

(Just as a footnote to the above, it seems Tesla 'switched off' Dyno mode sometime around April 2020 - see here )

You get a moving bar but its got no numbers on it in the same way as on the MS and MX.

Teslamate tells me the most power I've used recently is 377kw, which is 505bhp on my M£ LR with Acceleration boost. I presume thats battery output not wheel power but that type of complexity happens with ICE (equivalent to crank v wheel power).

Max motor power is in the Users Manual…. Rather than google random websites for the answer

 

[btc1k]

From the users manual and converted from max kW

SR+ 320 bhp
LR 434 bhp
LR +AB 484 bhp
P 505 bhp

"How much BHP does an M3 make?"

Enough

 

[MrT3]

Max motor power is in the Users Manual…. Rather than google random websites for the answer

It gives max power for each individual motor but can the battery pack and inverter supply the full power to both motors at the same time? Also the max power of front and rear motors are at very different speeds, is the gearing matched so they both produce max power at exactly the same time so you can easily calculate the full vehicle power?

, is the gearing matched so they both produce max power at exactly the same time so you can easily calculate the full vehicle power?

I have been led to believe they deliberately do not in order to maximise the performance through out the speed range without the need for a multi speed gearbox like say a Taycan has.
